Colorimetric Tubes

Thin Tubes
When measuring concentrations of specific compounds, nothing quite beats the colorimetric tube for simplicity, flexibility and specificity.
The Uniphos air-sampling pump is a one-stroke pump with built-in tip breaker and shard reservoir. This ensures safe and clean working and guarantees a reliable analysis.
Uniphos offers tubes for most compounds, often in multiple measurement ranges. Most tubes have a shelf life of up to 2 years.
Uniphos tubes and pumps are compatible with RAE Systems LP-1200 / Sensidyne™ / Gastec™ GV/100, 800 and Kitagawa™ 8014-400A pumps. The tubes of these manufacturers are compatible with the Uniphos sampling pump as well.

Thick Tubes:
Complementary to thin tubes, we have also available MSA/KWIK-DRAW thicker tubes, compatible with DRÄGER sampling pumps. These tubes extend the range of gases and measurable ranges available.
